I want to eliminate certain observations in a large dataframe (21000x100). I have written code which does this using a binary vector (0=delete obs, 1=keep), but it uses for loops, and so it's slow and in the extreme it causes R to hang for indefinite time periods. I'm looking for one of two things: 1. A document which discusses how to avoid for loops and situations in which it's

Hi. I want to use R with very large files, a couple hundred megabytes, but R crashes every time that I try. Reading help files seems to indicate that R ought to manage its memory itself. I know I have enough memory since stata handles these files perfectly well. I have a mac running OS 10.3 and am running RAqua 1.8.1. Is there anything I can do to make it deal with these files successfully?

I have a question for our European readers: how common is it to use commas as decimal points in spread-sheet and statistics applications? Is it an inconvenience to require that all data use a period as decimal point? (i.e., 3.14159 rather than 3,14159). We're trying to make our program as foolproof as possible, and would prefer not to give users a chance to have commas as both decimal

Sorry, my question is if exists a command tkexit in R, i need a command how exit of tcl for close an aplication. How to use him. Thank

Windows (both XP and 98) seems to have a problem with our GUI, written using R's tcl/tk package. When we open another window, and then return to the GUI, the GUI has old pieces of text left from the previous windows and/or places which are cut off where a window had been. Also, when it computes something, the window will often decide to move itself over for no apparent reason, so it moves

Hi. I'm trying to install a new package. I'm a relatively long-time (though not advanced) R user and have never seen this error before. For the first example, I tried a few different CRAN mirrors. In the second example, the file does exist; I downloaded it from the CRAN website for the package and pasted in the name exactly a few different times to make sure it was right. >

How does one put quotes within quotes, if it's possible? I've tried replacing one set of the quotes by single quotes. If it's not possible, is there any way to do the following? > cmd <- "read.dta" > opt <- "convert.factors=FALSE" > data.file <- " file="/full/path/name.dta" " > eval(call(cmd,data.file,opt)) Prior to

I hope someone here knows the answer to this since it will save me from delving deep into documentation. Based on 22 pairs of vectors, I have noticed that tetrachoric correlation coefficients in stata are almost uniformly higher than those in R, sometimes dramatically so (TCC=.61 in stata, .51 in R; .51 in stata, .39 in R). Stata's estimate is higher than R's in 20 out of 22

The R documentation for some of the foreign package's functions says that the set of variable labels becomes attributes in the resulting data frame. Thus, e.g., 5="strongly agree", 4="agree", etc. I'm happy that the labels are being passed, but unfortunately, when R summarizes the data, it will list it only as categories, and doesn't deal with the

You might look at "eval" and "parse".

Dear Samba Team, I have this error executing the smbclient program on a SCO Unix Open Server 5.0.2 : dynamic linker : smbclient : error opening /usr/local/lib/libncurses.so.4 Killed I checked it, but I don't have any library with that name. What can I do? Thanks & regards, Fabian Bustamante CARTOPEL GROUP Cuenca - Ecuador.

I'm in the very initial stage of expanding the formula processing in my quantile regression function rq() to handle additive nonparametric components, say qss(x), or qss(x,z). I need some advice about strategy for formula processing. My initial foray was to use: terms(formula,specials="qss") and then modify the components of the resulting terms.object. But in changing formula

Hi, I'm new to R. I was wondering if anyone has an OS X native installation (not Carbon) of R on a G3 Macintosh that is able to run linear regression? I installed Jan de Leeuw's R binary for OS 10.2 Jaguar on my laptop, which is still a G3 model. When I try to run a simple regression, using lm, I get an "Illegal Instruction" message and R quits. Jan thinks it may be the case

Dear all, I get a strange error when I find polychoric correlations with the ML method, which I have been able to reproduce using randomly-generated data. What is wrong? I realize that the data that I generated randomly is a bit strange, but it is the only way that I duplicate the error message. > n<-100 > test.x<-rnorm(n, mean=0, sd=1) > test.c<-test.x + rnorm(n, mean=0,

Hi. Does anyone know whether the following error is a result of a bug or a feature? I can eliminate the error by making ML=F, but I would like to see the values of the cut-points and their variance. tmp.vec<-c(0, 0, 0 , 0 ,0 , 1, 0, 2, 0 , 0, 5 ,5 ,3 ,1, 0 , 1, 5, 10, 27, 20, 9, 0, 1, 1, 12, 29, 57, 34, 0, 0, 1, 2, 11, 31, 32) tmp.mat<-matrix(tmp.vec, nrow=7)

Hi, i have been running R 2.11 compiles with the goto blas libraries successfully for about a year. I am running Ubuntu 10.10 64 bit. However, recently I have been periodically getting a segfault when running R (and numpy -- also compiled against goto blas). When I check the dmesg error log I get the following message R[28792]: segfault at 7f4183ed4000 ip 00007f4196f05f03 sp 00007f4192d55d20

Hi, I am running Linux (64 bit) R, compiled under gnu compilers. I am looking to compile a Fortran program with the ifort (the intel compiler) and then be able to import that as a library into my version of R. I am using the flags FC=ifort and SHLIB_FCLD=ifort, however ifort does not seem to recognize the libR.so file. Does any one have experience with this/know of a a way to load an ifort

Hi, I am trying to use the merge command in the data.tables package. However, when I run the command I am not sure if it is running the merge command from the base package or the merge command from data.tables. When I run "methods(generic.function="merge")' it informs me that 'merge.data.table" is "non-visible". I am just trying to run the merge command on two
